Scientists discover a key signal in intercellular communication

A team of scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), led by Prof. Francisco Sánchez-Madrid, has characterized a cell signal that impedes intercellular communication and could ...

Research team identifies key step in process of Shigella infection

Researchers from the Massachusetts General Hospital (MGH) Division of Infectious Diseases are investigating the mechanism by which several important pathogenic species of bacteria deliver proteins into the cells of the organisms ...

A bacterial ballistic system

Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have determined the structure of a crucial part of one of these ...

The dual significance of bacterial protein secretion

Secretion of bacterial proteins is an essential biological process with biotechnological and biomedical impact on human health. European scientists studied a universal and widely conserved bacterial secretory pathway towards ...
